【Objective】 To conduct the laboratory quality assessment between 12 blood stations in Hebei province, analyze the results and explore the accuracy and comparability of testing, so as to improve the level of testing ability and quality management. 【Methods】 With reference to the external quality assessment rules of National Center for Clinical Laboratories and combined with the instructions of quality assessment samples, daily testing process of the laboratories were assessed. The quality indicators include blood cell count (WBC, RBC, Hb, HCT, MCV, MCH, MCHC and PLT), biochemical items (TP) and coagulation parameters (FIB and FⅧ). 【Results】 There are still problems in laboratories in terms of personnel operation, instrument maintenance and the impact of different reagent batches, especially in biochemical items and coagulation parameters. The pass rate of biochemical items was the lowest, only 72.75%, and that of blood cell count was the highest, reaching 98.75%. 【Conclusion】 With the progress of the project, the quality monitoring level of daily blood sampling tests in the quality control laboratory of each blood station has been improved. However, it is still necessary for each laboratory to improve the testing ability and quality management to a higher level in Hebei.
